Astrophysical Parameters (gaiadr3.astrophysical_parameters)
The table has 1590932717 rows, 226 columns.
Description
This is the main table containing the 1D astrophysical parameters produced by the Apsis processing chain developed in Gaia DPAC CU8 (see Chapter cu8par). Additional parameters can be found in table AstrophysicalParametersSupp.
Known issues
Missing bolometric correction for some sources
Upon validation of the data, a minor processing bug was discovered in the FLAME software which resulted in a list of 153,474 sources that have valid FLAME parameters but for which the associated field bc_flame is set to null. The user can recover these values by using the bolometric correction function which is provided as part of the astrophysical parameter tool which is available on the Gaia DR3 software tools webpage. For more information, see Creevey et al. (2022).
Small set of GSPspec results out of validity ranges and with wrong extrapolation flag
The flags_gspspec chain includes a specific character named "extrapol" (c.f. Table 2 in Recio-Blanco et al. 2022) that controls the extrapolation level of the GSPspec parametrization. A bug in the implementation of this "extrapol" flag has left 251 sources with at least one extrapolated parameter and values outside the corresponding validity ranges. The list of Gaia DR3 identifiers of these sources is in the attached file.
